UNITED STATES HENRY NAGEL, OF NEW ORLEANS, LOUISIANA.

HUMIDIFYING Application ied May 10,

To @ZZ whom t may concer/n:

Be it known that I, HENRY NAGEL, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in a I-Iumidifying Attachment; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a humidifying or moist air supplying attachment for internal combustion engines and fuel systems.

It is aimed to provide a novel eflicient and inexpensive means to accomplish the end stated which will effect a substantial saving in fuel.

It is furthei1 aimed to provide a construction in which the moist air is admiXed with a separate source of air supply, preferably filtered, in order to effectively vaporize the mixture and prevent the use of moisture in too great a quantity in proportion to the air.

The invention resides in the novel construction, arrangement and combination of the parts accomplishing` the novel result and advantages hereinafter set forth.

One practical embodiment is illustrated in accompanying drawings.

In said drawings Figure 1 is a plan view showing my improvement associated with an internal combustion engine, the latter being frag mentary;

Figure 2 is a side elevation of the parts of Figure 1;

Figure 3 is an end eleva-tion of the parts forming my attachment alone;

Figure 4 is a vertical sectional view through the water receptacle taken on the line 4--4 of Figure 1;

Figure 5 is a longitudinal sectional view through the air strainer device; and

Figure 6 is a detail perspective view illustrating the means for manipulating the valve employed.

Like reference characters designate like or similar parts in the different views.

As the invention is principally though not necessarily, used in connection with internal combustion engines of the vehiclepropelling type, such an engine has been suggested in the drawing as at A of which the intakel manifold is designated B. The dash board of ATTACHMENT.

1922. Serial No. 559,971.

an automobile with which the engine is associated is suggested at C.

In carrying out the invention, a receptacle is provided at 10 adapted to contain water at a predetermined level and to this end being provided with an outlet valve as at 11 which may be opened while the container is filled so that water above said level will drain from the valve 11. After draining, the valve 11 may be closed. This receptacle may be filled in any suitable manner and by way of example may have a filling spout at 12, adapted to be normally closed by a plug closure 13. Said spout 12 is provided at the top wall 14 of the receptacle and secured to said wall 14 is an air intake tube or conduit 15 which extends exteriorly above the wall 14 and which terminates relatively close to the bottom wall of the receptacle and stops below the level of the water therein with its lower terminal portion coiled as at 15a. The wall 14 is provided with an outlet opening surrounded by a nipple at 16 as shown.

The said receptacle or tank 10 may be made of any suitable material for instance, copper. Also, the receptacle 10 may be located wherever desired on the automobile and for instance at the rear of the said dash board C by means of an attaching bracket 17 carried by the receptacle and bolted or otherwise fastened at 18 to its support.

In communication with the said intake manifold B is a pipe or conduit 19 having one end in communication with the atmosphere and with the opening at said end covered by an air strainer 20. The air strainer 2O may be of any suitable construction but is preferably of metallic gauze soldered or otherwisel secured as at 21 to the adjacent end of conduit 19. Tapped in the conduit 21 is a Tooupling 22 to which a conduit 23 connects and which leads from the nipple 16. This conduit. may be of any suitable material but is preferably of a flea'.- ible nature and may be rubber tubing preferably slipped over the nipple 16 and the attaching part of the coupling 22. The con nection between screen 20 and conduit 19 is considerably smaller than pipe 23 so that pressure will be exerted at the top of tank 10.

Connected in the conduit 19 intermediate the coupling 22 and the manifold B, is a suitable type of throttle valve 25 having an operating stem at 26. As it is desired that the valve may be operated from the drivers seat, the manipulating rod is providedl at 27,L detachably connected ati 28 to the rod 26, and slidable through an appropriate opening 28a in the dash board C. In front of the dash board, the rod 27' may have a rosette or other manipulating; handle 29.

In operation of the engine or motor A, a partial vacuum will. becreated. through the manifold B, the conduit 19, conduit 23 andthe tank 10, causing air-'toi be drawn in through the conduit 15a andthe Watery in the tank 10, whereby it will' be etl'ectively Washed. The air will then be drawn through the conduit 23 and conduit 21.. It Will ve realizedl that the air thus drawn into the conduit 23-Will be vapor-laden or moist and When it discharges. into the conduit 21 it Will-be in that condition. Simultaneously, air isdraw-n in through, the strainer at 20 into-conduit 19,. intimately admixing with the air discharging into the conduit 21 from the conduit 231s@ asl to ei'ectively: atomize the moisture contained in the air. Such atomized mixture is then drawn intovthe manifoldI B through the valve 25. The latter being completely opein or appropriately this attachment functioning in the mannen stated,` effects a. saving 1n fuel; and substantially eliminatescarbon trouble in the motor.

iks merely one practical?. embodiment has been. illustrated andv described, it is to be understood that changesin` the detailss may be resorted to provided they fall Within the spirit and scope of the invention'.v

Havingthus describedthe invention, what I claimrisz- 1. In a humidifying attachment, a conduit tor communication with the fuel intake means of an internal combustion engine, a Water container, a conduit in communication With.- said conduit and With said container, means on the container communicating with the atmosphere for passage of ainthrough: the Water and thence through the secondl mentioned conduit, thesecond mentioned conduit being in: communication with the-atmosphere beyond its junction with: and" atlanfl angle to the first mentioned conduit.

2. Ina humidifying attachment, av conduit for communication with the tuel intake means of any internal'combustion engine, a

Water container, a conduit in communication With saidA conduit and with saidcontainer, means on the container communicating with the atmosphere for passage of air through the Water and thence through.. the second mentioned conduit,.. the second mentioned conduit beingzin communication With. the atmosphere beyond its junction With and? at an angle to the rst mentioned conduit, air straining means: at the free endv ot the second mentioned'. conduit,` and a throttle valve in the'irst mentioned conduit between thepoint of connection Withcthe second mentioned conduit and. the fuel intake means. In testimonyl WhereofI affix. my signature in. presence ofi two Witnesses.
